A Comparative Study Of Chinese And American High School Physics Textbooks Based On Core Literacy

In 2017,China's newly published "general high school physics curriculum standard" stipulates that the goal of the high school physics curriculum is to promote the cultivation and development of the core literacy of the physics discipline,and teaching materials are the concrete manifestation and realization of the curriculum goals.In order to cultivate the core literacy of physics,our country needs to attach great importance to the writing of high school teaching materials.The author first takes the "force and Newton's Law of Movement" part of the physics textbooks of China and the United States as the research object,and takes the theory of the core literacy of the physics discipline,the relational learning theory,and Piaget's cognitive development theory as the theoretical basis.Using the methods of literature analysis,comparative study and content analysis,the author compares and analyzes the teaching materials from the aspects of column setting,knowledge construction,experiment setting and problem making.Then based on the core literacy from these four aspects of the comparative analysis of teaching materials results;Finally,according to the conclusion of the comparative analysis of the teaching materials,the author puts forward the suggestions of writing the teaching materials in these four aspects.Based on the core literacy of physics,the author compares the "laws of force and Newton motion" parts of Chinese and American physics textbooks,and concludes that:(1)compared with Chinese textbooks,the columns set up in American physics textbooks are more colorful and complete in structure.(2)Chinese physics textbooks pay more attention to systematic learning of knowledge,but ignore the students' acceptance ability;The knowledge construction of American physics teaching materials is gradual and more in line with the students 'cognitive laws.(3)Compared with Chinese textbooks,there are more exploratory experiments,student experiments,and quantitative experiments in American physics textbooks.The experimental content is more inclined to life practice and the experimental link is more perfect.(4)Compared with Chinese teaching materials,American teaching materials have manynew forms and exercises.The number of exercises is large and the level is clear.Students are gradually allowed to analyze and reason problems.In short,American physics textbooks can promote the formation of core literacy in the discipline of biology.According to the conclusions of the comparative analysis of the teaching materials,the author puts forward the following teaching materials to write suggestions:(1)In terms of column setting,supplement the learning resources,such as adding the columns of the recommended learning website;Add a column similar to the "section" preface to each section;Add review section at the end of the chapter.(2)In terms of knowledge construction,the applicability of children's teaching materials and changes the order of knowledge arrangement of teaching materials;Pay attention to inter-disciplinary links and supplement the necessary mathematical knowledge.(3)In terms of experimental settings,more exploratory experiments are set up to cultivate students 'innovative ability and analytical ability;The experiment content selects the common situation in the student's life.(4)In the preparation of exercises,increase the number of exercises,enrich the form of exercises,distinguish the levels of exercises,and enrich the contents of the exercises.
